    Abstract:
    OBJECTIVE: The aim of this study was to show the incidence of synchronous lesions in colorectal cancer patients treated surgical at our service. SUMMARY BACKGROUND DATA: Many studies have shown different incidences of synchronous lesions in colorectal cancer, mainly due to variations in the accuracy of the diagnostic methods used and the intentional search for associated lesucosal. METHOD: Fifty-eight clinical records of patients operated on for colorectal cancer were retrospectively reviewed from August 1995 to March 1999. The synchronous lesions were classified as benign or malignant lesions based on its histological classification. Statistical analysis was carried out by the Spearman coefficient correlation. RESULTS: Fifteen patients (25.8%) had 28 synchronous lesions, nine were male (60%), and six females (20%). The average age was 63.2 years with a range of 26 to 83 years. The endoscopic diagnosis of synchronous lesions was performed preoperatively in 12 patients (80%). The most frequent localization's of primary tumor was the sigmoid colon in six patients (40%). The more frequent localization of synchronous lesions was the rectum (35.7%). Benign lesions were most commonly found in synchronous lesions (89.3%). CONCLUSIONS: The patient with colorectal cancer has an unstable epithelium and an uncommon predisposition to develop several mucosal alterations. This predisposition is prone to grow benign or malignant lesions. For this reason, we advise all that patient with colorectal cancer be fully studied endoscopically.
